Are hot dogs classed as a sandwich? We freeze buttered hot dog rolls from the bakery in groups of 2 or 3 (depending on how hungry he is) and in the mornings he just grabs a some of these with a few frozen footy franks and heats the footy franks up at work in the microwave with a bit of water. He has a bottle of tomato sauce which he keeps at work for his hot dogs.

We also have lunch-size portions of spag bol and different curries in the freezer in disposable chinese food containers which can be easily heated up at work in the microwave as well as Lean Cuisine/Weight Watchers meals. In the past (before our diet days) we used to buy a packet of Four n' Twenty Steak Pies and DH used to take these to work and heat up too.

DH loves his sangas so lately I have been making 10 x corned meat and pickle sandwiches and freezing them and he just grabs two of these each morning.

I'm lucky that DH loves cooking so sometimes he will make a HUGE pot full of stew or curry or curried sausages which he will freeze and this will do for his lunches for a few months.
